Yes, it is today. However, the actual services begin at 6pm (18:00) Luxembourg time according to the signs posted in front of the cathedral. It is not yet even 12:30 in Luxembourg. No sign of the GD family yet. The procession that will proceed the services also hasn't started.

The first gallery of photos has been posted on RTL. It does not YET include any photos of the GD family, as they don't seem to have made an appearance thus far. The gallery will be updated later in the day.

Hopefully, as the week goes on more pictures will emerge. Tom Wagner finally loaded pics of the Octave preparations from earlier so perhaps he will load pics from the actual Octave Procession. There is a small piece on Wort.lu with a nice picture, but otherwise the RTL gallery is it. The GD website usually updates in the afternoon so hopefully they'll also put up a pic or two.

I missed seeing Guillaume there. He must have something important going on for him to miss the Octave of Our Lady of Luxembourg.

Thank you for all the pictures! It's great to see the Luxembourg royal family together, especially Gabriel and Noah joining them on the balcony for the first time. The little boys are so big and really cute!
